Bioremediation of Lead and Cadmium by Tea Waste
Heavy metals released by a number of industrial processes are major pollutants in marine, ground, industrial and even treated waste waters. Biosorption is a process that utilizes biological materials as adsorbents and several researchers have studied this method as an alternative technique to conventional methods for heavy metal removal from wastewaters. In this study, the efficiency of tea was...
متن کاملZinc , Copper , Lead and Cadmium Contents in Japanese Green Tea
There has been a remarkable increase in the interest shown to trace metal contents in various foodstuffs, since various heavy metals have been shown to be invariably present in environment and in the foodstuffs with the development of analytical methods and techniques. Lead and cadmium have been recognized as important environmental pollutants with toxic effects on human at relatively low level...
متن کاملRemoval of heavy metals (lead, cadmium, zinc, nickel and iron) from water by bio-ceramic absorbers of hydroxy-apatite microparticles
Heavy metals are highly poisonous in the environment, even in small quantities, and endanger certain species and all live beings. Current methods of removing heavy metals from aqueous media include chemical sequestration, ion exchange, surface absorption, membrane processes, oxidation and revival procedures which have high investment and exploitation costs. Hence, it is significantly necessary ...
متن کاملRemoval of Pb (II) from Aqueous Solutions Using Waste Tea Leaves
Background: The presence of lead in natural waters has become an important issue around the world. Lead has been identified as a highly toxic metal that can cause severe environmental and public health problems and its decontamination is of utmost importance. The aim of this work was to evaluate the adsorption of lead (Pb(II)) on waste tea leaves as a cheap purification method. Methods: In thi...
متن کاملRemoval of Cadmium, Zinc, Lead and Copper by Sorption on Leaching Residue from Nickel Production
Odstránenie Cd, Zn, Pb a Cu sorpciou na vylúhovanom zvyšku z produkcie Ni A leaching resudue from the nickel production (LRNi), was used to study the removal of selected bivalent cations (Cd, Pb, Cu and Zn) from model aqueous solutions. Batch-type experiments have been performed in solutions with initial concentrations of heavy metals in the range of 20-400 mg.L and the adsorbent dosage 2 g.L. ...
